Considering the true nature of what addiction is, I wouldn't think 'addicted to escorts' is a real thing in a general sense... Perhaps the examining the implications behind someone's habitual need to visit escorts could explain why someone seeks the constant affections of an escort. Like:
- Are you a middle-age guy grasping at youth by hiring a provider that's young?
- Are you lonely?
- Do you like having that <thing> done to you/for you that no other regular woman would do under normal circumstances?
- Just need that excitement in your life.
Otherwise, addictive behaviours relating to this 'hobby' is something that is inherently damaging your well being, like:
- Not using a condom, or become ignorant of a provider's health condition, or your own.
- Exposing too much of your personal information, doing away with discretion.
- Or allowing yourself to be dragged into a providers personal problems, thinking you get freebies.
- Not doing enough diligence on the providers 'age' or your own legal standings.
- Not self-aware of your surroundings, prone to be caught in public places.
